When you go to start the gear select D4 dash light will flash and the car will crank over but wont start
Okay everybody...i did it myself....replaced the main relay and the TCU box..but i didnt use another OKI manufactured TCU..i bought the Denshigiken manufactured one....(this was a 2nd manufacturing of the TCU)....when it first arrived today i opened the module up to check the resistors and capacitors...and noticed the completely different configuration and parts inside...this worried me..but i hooked it up anyways...to my amazement all problems vanished ..and everything works now..(cruise control, shift interlock, D4 light, tranny shift, brake light, intermittent no start, everything that was wrong..must have ran through this stupid little resistor) ......i solved his problem for less than $100.00..and less than an hours work....i can get more of these Main relays and TCUs if someone needs or needs help locating and removing/installing new pieces...email me at [email protected] or call me @816-286-8851..ill be glad to help
Main relay ........$10.00..
TCU................. $80.00...
10mm deepwell ...$4.00
Probably the main relay, as posted earlier, it's under the dash by the fuse box, kind of tricky to remove. If you're good with a soldering iron, you can pry it open and resolder the solder joints to repair it and save yourself $80.
Heat/stress cracks form in the solder which makes bad connections in the relay.
I had the same problem with my wife's car, D4 light blinking, wouldn't start, if you played with it long enough the light would go out & car would start - BUT- if the light came on with the car running it wouldn't shift correctly & might go dead or act like there was water in the gas. after talking to all types of Honda repair people, i sat down with a repair manual & traced out all the wiring for the fuel pump, fuel injectors, transmission controls, everything kept coming back to the main relay (main fuel relay, PGM main relay) (NOBODY SEEMS TO CALL IT THE SAME THING TWICE). It's located under the dash, over the steering column, mounted to a little bracket the it mounted on the underside of the dash. Replaced the relay, no more problems - been over 2 years now.
Try to disconnect the hose going to the valve cover see if the lights would still come on. Mine had check engine lights on and D4 keeps flashing. I did what ive mentioned and both of the lights went out! I end up replacing the air filter and cleaning the throttle body, it works fine now!
When the "D4" light flashes it is indicating a problem with the transmission! Go to AutoZone or Advance and let them pull the code for you. It could be one of many different parts that are bad and/or a TCM(Transmission Control Module). I am a ASE Certified mechanic! There could be other things going on at the same time, without detailed accounts no car can be diagnosed over the internet! My 92 Accord, which is fuel injected, unlike the 90 Accord had a bad TCM. I had to replace it ( about $200 dollars from AutoZone) Dont buy one that is not remanufactured or new! If you get one from a junk yard it WILL go bad too! And just to clear things up...It is nearly impossible for a Fuel Injected car to become Vapor Locked! Carburetor's are very prone to the problem however!
After many suggestions, I have come to the one and only solution to the Honda starting problem. I have two 92 honda accords and they both had the same problem. It is called a main relay. It cost about $80.00 @ the Honda dealer. It is roughly the size of a D battery but rectangular in shape and is gray with a female plug for a 7 wire jack. There is a small metal bracket that comes attached to it. Located under the dash, NOT buy the fuse box but up by the steering column. When I changed it out, I never had the starting problem ever again. Now the D4 maybe a different thing. Check the metal computer box on the passenger side floor board.
Hey guys ...i got same problem...and doing a research, i am almost sure that shift lock solenoid is the problem and should be changed...going to junk yard today to get it and replace it...asking ppl,it costs 80-100$ ....
TRY TO REMOVED THE POSITIVE BATERRY CONNECTION FOR ABOUT 5 TO 10 MINUTES THEN CONNECT IT AGAIN, CHECK IF THE D4 LIGHT WAS STILL ON WHEN YOU START. IF STARTS NORMALLY FOR THE TIME BEING, I GUESS THE PROBLEM IS ON THE A/T CONTROL UNIT.
The D4 light comes on, but it is, in my case, transmition related. The transmition only runs in either 1st and 2nd or 3rd and 4th when it comes on. Ran fine when I replaced the AT control valve assembly but didn't stay off long, it does start though. Just assumed this light was transmition related.
It should start if you push the accelerator to the floor.

you have a transmission fault the D4 light blinks to tell you that there is a transmission problem when the light is blinking the transmission computer put the transmission into limp home mode so it will not shift normally and you should try not to drive it very far when it gets to this stage you need to have the transmission codes check to pin point the problem

car turns over an D4 flashes wont start
cranks but wont start
I work at a apartment complex and i drive my honda accord lx for work. I travel from apartment to apartment on a good day i might visit 10 to 15 different units. So which means iam starting my car alot through out the day. Latley i'am makeing it to 1 to 3 and sure enough i come out hop in my car, then i try starting the car, but all it does is turn over but won't start.
My son called me the other day and said his 92 Honda Accord wouldn't start, that the D4 light was on and it just cranked over. What would cause this? First time that problem occurred. Any idea?
hadn't started the car in two months. charged battery. cranked over but wouldn't start. held foot to floor, still wouldnt start. added approx 1.5 gal fuel, tried again. no luck. noticed D4 light flashing. pulled plug on fuel rail and there was no fuel. couldn't find a fuse or relay for the fuel pump.
I have the same problem with the D4 light coming on. However, if you are getting fuel and spark, it shouldn't be the main relay. According to Honda the main relay is a dual relay the powers the ECU and the fuel pump. According to the dealer there is definitely something wrong with the transmission.
wow!!!! what a P.O.S. these hondas accords with AT are!!!
ive been having the same problems as everyone else except mine are intermittent.....D4 light stays on...cranks with no start...shift solenoid not engaging...pulled TCU apart and found burnt resistor...pulled main relay and banged on it with handle of screwdriver..fixxed all problems for a day...next morning..right back to where i started...im gonna replace these two pieces (with reman off of ebay) for about $100.00..ill keep everyone posted on outcome [email protected] (fingers crossed)
I have a 92 Honda Accord EX.Have checked and repalced what ever part I found to be bad.I used a Haynes Repair Manual.And I have checked and double checked all of the test.But the car cranks just like normal very strong but noyhing.I have checked to see if I get a spark but I don not.Please let me know what you think it could be.
What is a D4
i opened the car dorr thru the window and it set off the alarm
the car wont start because of anti theft and need to get car to start
